Abstract

The aim of this study was to compare the following 3 methods of assessing alveolar ridge dimensions prior to placement of dental implants: 1) ridge mapping measurement before surgical flap reflection using a caliper; 2) direct caliper measurement following surgical exposure of the bone, and 3) measurement using images from cone beam computerized tomography.

Sixteen subjects having 25 sites for planned implant placement or ridge augmentation were recruited. An acrylic stent was fabricated for each patient. The stent provided 3 buccal/lingual pairs of consistent measurement points for each implant site, located 4, 7 and 10 mm from the summit of the alveolar soft tissue crest. Two independent examiners participated.

Comparisons of bucco-lingual ridge width using ridge mapping vs. direct caliper measurements showed that 95% and 86% of the pairs of measurement deviations were within ±1 mm for the 2 examiners respectively. Corresponding comparison of NewTom image vs. direct caliper measurements showed 77% and 51%, and for ridge mapping vs. NewTom image measurements 79% and 66%. The reduced level of agreement when NewTom image measurements were included could be observed from the larger standard deviations of the series of pair-wise differences due to the presence of some large deviations (3-6 mm).

In conclusion, ridge mapping most often provides measurements of the buccolingual ridge width consistent with those obtained by direct caliper measurement following surgical exposure of the bone.
